question about mobil one oil

[locchamp]

Hi I am thinking about trying out mobil one extended performance, the oil that sopposedly goes for 15k does anyone have thoughts about this? And my most important question is if I do use this oil would it be okay to use a regualr oil filter such as ac delco? Some one told me that u need mobil one oil filter but i asked the store and they said no. Thanks

[Soron]

Most filters work with synthetic oil no problem, the oil is designed to last that long but oil filters are not, just remember to change the filter every 3000-6000 miles and top off and you should be good.

Since you are considering the change over to synthetic oil, might I ask how many miles you have on your car? if it has too many miles on it I would not recommend the shift over to synthetic.

[2loud2k2xd]

i swapped my oil to mobile1 at 64k when i started to spray nitrous. and the engine is well taken care of as far as maitinence and such.
i know there is an issue of going to regular oil to synthetic, the back to regular oil and having the gaskets/seals leaking.

[Soron]

Gasket/seal leakage is actually caused by the dino oil, synthetic oils have a natural solvency action that cleans up the crap that dinos leave behind and uncover the holes that the dino sludge has been covering up all that time, if someone was running synthetic since day one, 99% of the time their seals would still be good if they switched to dino although you wouldent get the same protection/performance of a synthetic.

[locchamp]

so you guys think mobil one extended performance is a good oil, it will last the 15k? does anyone use this oil? I drive liek a 500 miles a week so thats why i thougth it woudl be good so I do not have to change oil every month its gettign anoying thats why, but if someone knows somehtign about htis oil please tell let me know.I thought they were I do have a warranty so that could cause problems? DO I have to change the oil filter every 6k or can I take the chance I thought if u change the oil filter it will lea kall the oil, but if I have to change the filter then its the same as changing the oil really it did not save me any work. thanks

[southpawboston]

let's put it this way. the oil may stay good for 15k miles, but hyundai will NOT LIKE IT if you have an internal engine problem and they learn that you changed the oil every 15k. they will almost certainly be justified in denying you a warranty claim (for an oil-related problem). their policy is their policy, doesn't matter how good the oil is.

[Soron]

Thats true, the oil may last 15k but if its under warrenty you MUST change it every 7500 miles to keep it, (after 60k it doesent matter). It seems to me if your changing your oil once a month like you said @ 500 miles/week = 2k miles you're just wasting alot of money, for that I would recommend mobile 1 clean 7500 as its rated for that oci and using the extended 15k would just be a waste of cash. As for the oil filter, the rate of change depends both on its size and how often the manufacturer of the filter recommends changing it, the mobile 1 filters for our elantras can go thefull 7500 miles before a change, a k&n filter on the other hand can only go 6k, while $hitty fram filters wont last 3k.

[BlackElantraGT]

I am using the extended mobil 1 15K synthetic for the first time. Keep in mind that i've had mobil 1 synthetic since after my first oil change, so if your car has higher mileage, I probably wouldn't recommend the switch to synthetic. Even if you had a higher mileage engine and you switched to synthetic only to discover a leak somewhere, you could always switch back to regular dino oil.

Prior to the extended, I've used synthetic mobil 1 up to about 8K miles with it's mobil 1 oil filter. I've never had a problem. Synthetic oil changes gets expensive though, especially using mobil 1 oils and its oil filters, hence the reason I'm switching to the 15K extended. I have more than 60K miles on my engine so I'm not worried about the warranty. According to Mobil 1's website, you do not need to change the oil filter until you change your oil.

Soron emailed them and got a response from one guy working for Mobil 1, and the guy never specified that the oil filter was only good for only 7500 miles. He just gave Soron a number because that's what he wanted to hear. Mobil 1 has a FAQ about their new extended oils and the company itself tells you that you do not need to replace your oil filter until you change your 15K extended oil.

Being that you're in NY and you're driving more than 500 miles a week, you're probably driving a bunch of highway miles without much dust in the air so your car is driving in good, normal condition already.

Here's Mobil 1's FAQ:
http://www.mobiloil.com/USA-English/MotorOil/Oils/Oils_FAQs.aspx#Mobil_1_Extended_Performance_FAQs1

[locchamp]

thansk so blackelantra u are currently usign the mobil one extended performance (15k ) one with mobil one filter? How do you like it and have you gotten it to 15k yet? I have to use a mobil one filter right i bought a ac delco would that work or bottom line wil lit leak if it reaches a point? thanks

[BlackElantraGT]

According to Mobil 1 they say that it's not required that you use their filter, although they claim their filters are superior to others.

I've only had the extended performance for about 3K miles and I haven't experienced anything different with my car yet. My car has been using Mobil 1 Synthetic with Mobil 1 oil filters since its first oil change. I've used their oil filter for more than 8,000 miles previously and I never experienced any problems either. I'm sure that your oil filter would work if it's the right size, but I wouldn't know if it's superior to other brands or not. Leaking shouldn't be a problem as long as you got the correct model# for our car. The thing that we're all worried about here is the fact that the oil filter might not last as long as the oil itself, which is why Soron recommended to still change the Mobil 1 oil filter at 7500 miles. Mobil 1 says you don't have to, but a lot of people will probably change it during those 15K miles at least once for the peace of mind.

If your car is still under warranty, it just might be better to follow the manufacturer's recommended service intervals. I would hate to see your warranty be void for that reason. Personally, I think Mobil 1 knows a lot more about oil and oil filters than Hyundai or any of us. Porsche's, Corvette's, Evo's, along with many other brand new high end cars uses Mobil 1 Synthetic in their engines. These major car manufacturers use Mobil 1 for a reason, and it's definitely not to save money because we all know Mobil 1 isn't the cheapest. In the end though, Hyundai and its dealers are the ones honoring your warranty so despite what Mobil 1 says, I would follow Hyundai's guidelines just to be safe.

[Dust]

Run what Hyundai tells you, then when it's over, do some research on what you want to run, and then go from there. IF you want to go 10K miles, look into the Mobil 1 or the PureOne.

[Soron]

To keep the warrenty stay with hyndais recommended oci, oil and filter change like dust says, regardless of the oil you use (conventional or synthetic), M1's oil will last that long but if you do the oil change at 15k like M1 specifies, kiss your warrenty goodbye. After 60k run whatever oil you want at whatever oci you want. hope you dont have too many miles on your car as you never specified it, but general rule of thumb for switching to synthetic is, the more miles on it the more likely a leak has developed using conventional oil, general mileage guidlines are:

0-30k no problems
30-60k 5-10% chance of leaks
60-90k 10-20% chance of leaks
120k+ switch at your own risk (usually 30% - 50%+ at this point)

[2loud2k2xd]

even tho i run Mobile1 i will still continue to change the oil and filter at 3000 miles. mainly because i spray, but i get the oil FREE :) from the dealership i work at. but i do pay the oil change place to change the oil for me, this way i have all documented paper work associated to the oil changes and hyundai cant give me any ish about it.

[Bnystrom]

After 60k run whatever oil you want at whatever oci you want.
The drivetrain warranty is 100K miles, not 60K.

even tho i run Mobile1 i will still continue to change the oil and filter at 3000 miles. mainly because i spray, but i get the oil FREE :) from the dealership i work at. but i do pay the oil change place to change the oil for me, this way i have all documented paper work associated to the oil changes and hyundai cant give me any ish about it.
All that's required by Hyundai is that you keep a maintenance log, which is provided with the car. Keeping receipts won't hurt, but there's no way I'd pay to have the oil changed just to get a receipt.

Whether you get the oil free or not, it's still a waste of resources to change it at unnecessarily short intervals. If we were all more concerned about not wasting oil/gasoline, we wouldn't be so damned dependant on the Middle East for our supply. EVERY bit helps.

[Soron]

What does the drivetrain cover? I already knew about the 100k drivetrain warrenty but the bumper to bumper is 60k which is what most people are concerned with.

[2loud2k2xd]

the powertrain warranty (100k)covers the engine/trans/and other certain components that goes along with them.

[locchamp]

so bottom line what does happen to the oil filter if u just leave it for the 15k I mean what would happen if I got a peice of junk oil filter and just left in on my car what happens does it leak or break or do something really bad? thanks

[Soron]

If you leave the filter on there longer than the oci then there's a good chance that one of 2 things if not both happen.

1. The filter is full of contaminants and can't filter the oil anymore
2. The filtering media in it (i.e. paper, paper/cotton blend, or paper synthetic blend) will start to disintegrate, with synthetic media it will clog/be full long before it falls apart.

The mobil1 filter you should not have to worry about as it uses synthetic media and has a large surface area so it lasts longer (capacity wise), with a fram filter just kiss your engine goodbye, it all depends on the filters media, physical size/filtering area, and its overall quality, K&N filters for instance, though high quality, are made with paper and synthetic blend media and according to the rep. from k&n is only designed to last 6k but are easy to remove due to the welded on 1" nut and have a high burst pressure of 550 psi (the mobile 1 filter I believe is higher at 600 or so).

If you want to go with the 15k oil and mobil1's filter go for it, I see no real problems, just get an oil analysis done every 3k after hyndais oci of 7500 miles, unless the car is still under warrenty, in which case you MUST stick with their 7500 mile oci (best combo to use would be mobil1 7500 and their filter) to keep the warrenty in effect. If you want the absolute best oil in there, use royal purple, its very pricey but it quiet simply put is the best stuff out there.

[blupupher]

If your under warranty, just go with Mobil 1 and an OEM filter and change every 7500 miles and don't worry. Once warranty is up, you can try the Mobil 1 EP. For best results, get an used oil analysis done.

[Dust]

THe filter will one, clog up and go into bypass. letting oil flow but not filtering it. Two, it will rupture and a hole will occur in the filter media. Oil will flow but not much will be filtered.

[locchamp]

well i got a freidn that works at a garage they do oil changes he told me for the past 5 weeks hes been doign 3 t o4 changes with mobil one 15 kwith mobil one filter and they go they plan on leaving the filter i mea nmobil one garantees 15k
plus my friend has a hyundai accent and hes had mobile one 15k for 7k no he said its as clean as it was when he changed it
i think if garages are doing it with risk they can get sued it should be fine f*** the warrenty crap they always find a reason not to pay anyway why not be the oil lol
its always an excuse for warrenties my car has 12k on it and i am getting sick of changing the oil for so long how can oil ruin ur engine especially when the mobile one garantees 15k

[Soron]

Well if you're going to void your warrenty doing oci's of 15k thats up to you but don't run to the dealership when you need something else fixed thats under warrenty (such as o2 sensors or scratches in the paint as its all covered under warrenty) but thats only if they found out. I feel bad for ya that you drive that much but then again you change the oil way too often as well, since you drive 2k a month you don't really need to change it for at least 3.5 months and thats using conventional oil and a decent sized filter, not once a month like you have been doing.

[locchamp]

hey when are you soppose to ratate your tires I was thinking about doing it my car has 13k on it? anyone thanks

[BlackElantraGT]

you should rotate your tires between 6000-7500 miles. A good rule of thumb is every other oil change if you do ur oil changes every 3K miles.

[locchamp]

o hand here in ny state yo uchange your oil every 3k cheif its even stated by hyundai they told me I had to change it every 3k and thats what every one does in nys you have to dont ask my why its differant and void m ywarrenty how they goign to knwo what oil i got in there

[Dust]

what does your manual say aobut oil changes?

[mlumz]

chipped paint under warranty????

[Soron]

Tell me how a state law (ny) specifies oil changes at 3k? this is the first I have ever heard of it for ANY state, as states don't pay for warrenty repairs or maintanance that maintains manufacturer warrenties even the severe service for an elantra is 3.5k or something around there. As for how they can find out what oil is in there, simple, they can just do an oil analysis, they can tell right away if its synthetic or conventional, how long you have gone on that oil and a BUNCH of other info (like what contaminants are in it specifically), the average joe can spend $20-$30 for one, im sure dealerships or anyone doing expensive warrenty work on it can get it even cheaper.

[Bnystrom]

well i got a freidn that works at a garage they do oil changes he told me for the past 5 weeks hes been doign 3 t o4 changes with mobil one 15 kwith mobil one filter and they go they plan on leaving the filter i mea nmobil one garantees 15k

Can anyone understand this mess? Have you ever heard of capitalization, punctuation and spelling? If you want people you anwer you, it helps to write in an intelligible manner.

[locchamp]

bnystorm how do u spell go f*** urself? I didnt say that nys law i just said that you have to change your oil every 3k up northern us in ny u soppose to change every 3k. I dont know what the hostility is i mean man you guys are so rude to people i do not get all this from other websites i tell ya i am on other sites asking this same question no rudness there i guess i made the mistake here right. whatever go hump ur elantra loser. and ok if something happens to my engine and i have this oil for 10k right ok they say they will not fix my engine, so what is the differance then wether is under warrenty or not they still will not fix it and after 60k u have a better chance of it actually doing something bad to engine. its the stupid thing i ever heard. dont do it now wait till 60k after warranty why? ether way they will not pay so my lose, then i get mobil one to pay for it they say they will garantee my engine for 15k...what is the chances on getting any company to fix something under warrenty no one ever does they always find an excuse. I have bad luck with garranties. my couch after year broke will not fix, my rug after month will not fix, my bed after 5 months will not fix, so... bottom line when something major they will find everything and anything to say nope wont fix ur engine because u forgot to put windsheild washer fluid in ur container.

[southpawboston]

i still can't understand a word... :rolleyes:

let's lock this thread, my brain hurts.

[Soron]

We need both a translator and a lawyer here. Northern, Southern Western or Eastern U.S. it don't matter where you are, I do not believe there is a law among any of the states that specifies an oci of 3k as the states don't pay for repairs, upgrades and especially maintenance of privately owned vehicles, that is the responsibility of the owner and maintenance is even part of the contract you signed to keep the warrenty in effect with a vehicle.

If you have oil in your engine beyond the vehicle manufacturers oci then the warrenty is automatically voided no matter who manufactured your vehicle. Mobile 1 may warrenty your vehicles lubrication system from oil related failures when the vehicle manufacturer won't fix it, but first you must prove that it was their oil that caused the problem, very unlikely unless it's a known problem (internal knoledgebase to Mobile 1) to them.

Synthetic oil lasts longer and protects better than conventional oil, it's better to switch to synthetic (the less miles on the engine the better) but to keep the warrenty in effect you must change it at the oci the vehicle manufacturer specifies, in this case 7500 miles, even if the oil can last much longer than that. After 60k/100k miles you can use/set whatever oci you want as the vehicle is no longer under warrenty, so you can run Mobile 1 15k up to the full 15k rating of the oil if you want, but only after 60k/100k have passed on your odometer.

[2loud2k2xd]

listen, hyundai want you to change the oil at 3000 or whatever specified ammount of mileage for a reason. to keep the warranty i would do what hyundai says in their guidelines. i dont beleive any state has the right to mandate a specified mandatory oil change intervils. possible the state wants them done because over time the oil breaks down (wheather its syn or dino) for pollution reasons. i dont give a dayum what any state says, i go with what hyundai says. hyundai is the company warranting the car, not the state. this topic can can keep going one way or another.

bottom line, HYUNDAI covers the warranty, not the state.

[southpawboston]

^^^ what he said.

who's gonna pay for the repairs? hyundai? or the state? if it's hyundai, then do what they tell you to do. regardless of what brand of oil you use.

Dude, you need to chill a little. My head hurts trying to read your posts. They don't make sense with all the run-ons and such. I am no English Major, but come on.
Download THIS (http://www.iespell.com/) and use it with every post. Punctuation helps also.

As for your oil change interval, if you want to change every 3k, that is fine, but just because you live in a certain place does not set you to a certain mileage requirement, your driving style does.

[quickfingerz]

I just bought my second used Elantra. BOTH times on my first oil change on there were very small but visible metal shavings in the oil. They were both taken to "we'll change your filter next time" oil change places. They'll leave the filter and more particulates including metal shavings recirculate through the engine. I have never seen these shavings when I do regular oil and filter changes at 5K mi.

My oil change interval is every 5K mi. I save the reciept of my filter purchase. I either buy SuperTech 7317 or Purolator 14459, whichever is cheaper. I use SuperTech 10w-30 Full Synthetic oil in the 5 quart jug.

The only filters I trust going more than 5K mi are Mobil1, K&N, and AMSOIL. If you are changing your oil with anything less than 10K mi OCI, the difference from one synthetic brand to another will not matter at all.

[bfgoedeke]

That law that is being mentioned, is the biggest load..Second, there was research in regards to: oil changes and different brand oils...
1 - The maximum you can go between oil changes is about 7,000 miles regardless of any oil. Not that I would even do that.
2 - Consumer reports did a piece regarding different oil brands, and stated this; There was no difference between oils (except synthetics). They tested about 12 brands. Since they are all required to confirm to the same specs( AGI or API service). None performed any better then the other, cheap or expensive.
3 - Synthetics can handle abit more heat and abuse, but should be changed according to manufacturers directions. In this case 3,000 miles....

So what does it mean when I go 7500 miles (per the owners manual) and have an analysis done (http://users4.ev1.net/%7Enlhoyt/oil/blackstone.jpg) of my oil that shows it is still fine?
Don't start spouting off you opinion as fact unless you can back it up.

The comment about oils in general is pretty much correct. Some dino oils are a little better than others, but so long as they meet API specs, they are all decent oils. Price does not make the oil.

[newbie ninja]

what about royal purple claiming 12,000 between oil changes?

[Soron]

royal purple is a synthetic not dino, you also have to take into consideration that the 12k miles includes a/several filter changes with a top up which regenerates the oil every time, which is common for most synthetics.

[quickfingerz]

I haven't tried this, but can our filters be changed while leaving the oil in?

Good dino oil can easily last 7500 miles between changes. Synthetics can last 15000 miles between changes. That said I would never leave my filter on for more than 5000 miles.

[Soron]

yes, the oil sits in the oil pan, thats what it's there for, thats how you can change the filter and not the oil, unless you are changing the oil while the engine is still running or within 5-10 minutes of shutting it off lol. Most people change the filter anywhere from 3k to 6k which is how long most are designed for.

[Bnystrom]

Most people change the filter anywhere from 3k to 6k which is how long most are designed for.
Considering that the recommended change interval for oil AND filter is 7500 miles, apparently the filter is designed to last that long under normal use.

[Soron]

most filters are designed to last 3-6k because after that amount of time most filters are too clogged with gunk to filter as well as a new one, they do filter better but at a much slower rate and most of the time the filters go into bypass mode.

[Dust]

I think that most filters have proven themselves to go for 5K-7K on BItog. If you are concerned that your filter is already full, you can do it the easy way and touch it after you have driven for a while. IF it's not realy warm, your filter is in bypass. If that doesn't make you happy, send your oil in for test, and get a particle count.

[joehyundai]

USE THE HYUNDAI FILTER!!! Not only is it bigger, it filters better. I use mobil 1 (in everything) but the last time - against my mechanic's advice - I used a fram filter and my oil looks like sludge after only about 4500 miles....
It was also pointed out to me that he sees a lot of non hyundai filters leaking when they come in for service.

[quickfingerz]

Just buy the cheapest non-FRAM filter. I usually stick to the $2 Supertech but mostly use the Purolator ($0.99 after rebate right now).

[Dust]

But your engine will blow up and a Korean dragon will come out of your oil cap and eat you if you use anything other than OEM :eek:

[Soron]

ROFL!! god dust I remember when that happened to me last..... lol!

[Dust]

ROFL!! god dust I remember when that happened to me last..... lol!

My brother actually saw the dragon.

He was driving in Georgia in the rain, and the Korean dragon that was pissed off at him for using the wrong filter, jumped into his brake lines after causing the person in front of him to slow down, causing the totalling of the car.

The dragon would rather kill a car than make a car’s engine suffer through the wrong flow, pressures, media, temperature, killing of the user’s first born, impregnation of the user's younest daughter, and the weeping and gnashing of the warranty that comes with using the non-OEM, incredibly inferior filter.

And you get a earache.


The worst part is that they won’t validate your parking when you drive to headquarters to sacrifice 10 Hyundai filters for your trangressions.

Let’s not talk about what happened the last time my parents stopped in NO for a meal. They don’t have a daughter, but I had to find my good friend Goku over here, and he quickly gathered all the Dragonballs, and my life was saved. And I can live forever too. Thanks Goku!

Use a non OEM filter, live forever.

I hope everyone's questions were answered on this one.
